An arsenate (compound) is some compound that contains the arsenate ion : AsO43- . Arsenate is much like phosphate. In acid conditions we have arsenic acid, H3AsO4; in weakly acid conditions we have the dihydrogen arsenate ion, H2AsO4-; in weakly basic conditions we have hydrogen arsenate ion HAsO42-; and finally, in basic conditions, the arsenate ion AsO43-.
